Try to create an automatic cast or other conversion node node to facilitate a connection between two pins. It makes the cast node, a connection between A and the cast node, and a connection from the cast node to B.two This method is called when a connection is made where CanCreateConnection returned bCanAutoConvert.
True if a cast node and connection were made; false if the connection failed and had no side effects.
virtual bool CreateAutomaticConversionNodeAndConnections ( [UEdGraphPin](API\Runtime\Engine\EdGraph\UEdGraphPin) * A, [UEdGraphPin](API\Runtime\Engine\EdGraph\UEdGraphPin) * B ) const
